The vacuum tungsten sintering furnace is a vertical structure vacuum resistance furnace that utilizes tungsten mesh as the heating element. It boasts an ultra-high temperature capability of up to 2100°C and operates within high vacuum conditions, making it ideal for laboratory scientific research or industrial production purposes. This furnace finds extensive applications, including the sintering of high-purity ceramics into transparent ceramics, the melting and sintering of high-melting point metals, alloys, ceramics, and other materials, as well as the brightening and degassing of certain metals. Furthermore, it facilitates the measurement of the physical and chemical properties of metals and ceramics under high-temperature vacuum conditions.
Its insulation layer, designed with proprietary technology, ensures excellent furnace temperature uniformity, minimal thermal field deformation, and an extended service life. Additionally, this equipment offers the advantages of compact size and straightforward operation.
